Statistical and stochastic modeling methods were adopted to analyze, quantitatively calculate and predict carbonate reservoir fracture and vug character of Ordovieian reservoir in Tazhong Oilfield based on core, FMI and normal wireline log- ging data. The results show that fractures and vugs developed intervals are characterized by obvious low resistivity and maxi- mum amplitude difference, high interval transit time and low logging density. Fractures are developed in Yingshan formation, which makes fracture permeability become largely higher than matrix permeability. Fractures and vugs have obvious effects on reservoir reconstruction and flowing proterties.
